, The invention aims to provide an improvement in radiators b which they may be betterV and more quie ly controlled and regulated than heretofore. Jlhe accompanying drawings illustrate an embodiment o `the invention.

Fig. lis a perspective vieur of the complete radiator.

lFig. 2 is a transverse vertical section of the same on the plane indicated at 2-2, Fig. l.

Fig. 3 is a plan of an end oi Fig. l.

rlhe conduit for the heating medium comprises a pipe bent to iorm three horizontal lengths, l, 2 and 8 respectively, to provide a continuous passage for the steam, hot Water or other heating medium. The radiating structure is of sheet metal corrugated to form transverse inclined plates Il connected at their outer and inner edges respectively' by short longitudinal plates .5 and d. rThe inneredges of the corrugations, formed by the plates, are secured or bonded closely to the pipe lengths l, 2, 3, by heat and pressure; being thus soldered, braced or Welded to the pipes in the manner described in detail in the cri-pending application of Murray and Heier, No. 91,023, filed February 27, 1926. The inner portions 6 of the corrugated plates are preferably brought together or nearly so and may be united directly to each other. These plates are exposed to the atmosphere on the outside, and their inner faces form vertical nues to facilitate circulationoi the heated air. They may be made very thin and of considerable area and of copper or other metal of high conductivity. The securing oi them directly to the pipes provides the necessary stiffness with the simplest construction. They take the heat so rapidly from the pipes that the heating element may be maintained at a very high temperature, and a high eciency obtained.

With steam or hot Water heating it is diiiicult to bring the radiators to a high temperature quickly, chieily because oi the delay in bringing up the temperature oi a considerable body of Water. To provide :torquick heating l propose to supplement the pipes l, 2, 3 `with an electric heating element 7. This maybe any resistance or other usual or suit# able style ofelongated heating element generu ally carrying a coil of resistant material. l propose to arrange this element parallel to the lengths of the pipe, between two such lengths as illustrated, or it may be below the I lowest length o-pipe; and to secure it to the inner edges of the corrugations by bendingv out the latter as at 8 (Fig. 2) to embrace the heating element, to which the plates are united in the same wa as to the pipes. It thus increases the sti'tness oi' the radiating structure and conveys its heat rapidly thereto. rThe Wires 9 from its opposite ends are carried down to an electric socket 10 on one of the legs 1l of the radiator, for easy attachment to a base board socket. Or the electric heating element might be permanently connected to the house Wiring with a switch interposed.

NOW when a quick heat is desired the electric element can be heated to a high temperature in a 'few seconds and the discomfort usually to distribute the heat thereof sutil-f -ciently throughout a room. The present structure is particularly adapted to this use because of the good surface Contact of the corrugated plates with the heating element, the large radiating surface and the iues which cause the air to carry o5 the heat very rapidly. in tact several such heating elements may be employed in a single radiator with great efiiciency; and, Where electric current is cheap, they may be used Without the steam pipe.

An im ortant feature of the construction is the ma ing of the radiator in two separate parts; one, the continuous pipe 1n several lengths, carrying the pressure oiE the heating medium and the other, serving only as a radiating structure, carrying no pressure, and, therefore, made so light and thin as to make it possible to lighten the entire radiator.

N o claim is made herein to the electrically heated radiator exceptin combination with the other elements. The electric heater separately is covered in a divisional application No. 168,871 filed February 17, 1927.

Various modications may be made by those skilled in the art without departing from the invention as deiined in the follow,- ing claims. i

What I claim is 1. A radiator including in combination a horizontally extending heating element comprising a narrow elongated conduit for a heating fluid, an elongated electric heating element in substantially the same vertical plane and a radiating structure of extended area in intimatecontact with the outsides of both said heating elements at different points in its height and projecting laterally and vertically beyond said heating elements.

2. A radiator including in combination a horizontally extending heating element'comprising a narrow elongated conduit for) a heating iiuid, an elongated electric heatin element in substantially the saine vertica plane and av radiatingistructure of extended area in intimate contact with the outsides of both said heating elements at diil'eren-t points in its height and projecting laterally and vertically beyond said heating elements, said radiating structure comprising thin sheets corrugated in horizontal sectio'n so as to form vertical passages in which. the air is heated and thereby circulated, the inner rportions of the corrugated plates being bent to form recesses along the lines of the heating elements and embracing said heatingelements in said recesses.

3. A radiator including in combination a conduit for heating fluid, an electric heating element in substantially the ,same vertical plane providing a supplementary source of heat and a radiating structure of' extended area in intimate contact with the outside of said conduit and said electric heating element 1 and comprising a pair of corrugated sheets one at each side of the radiator with the corrugations registering with each other so as to form between them vertical dues closed in horizontal section for inducing a draft and circulation of the heated air and to' present at their outer faces vertical channels formed by their corrugations.' I In witness whereof, I have hereunto signed my name.
